To all whom i'may concern:

Be it known that I, CHARLES A. WULr,

l a citizen or the United States,'residing at Indiana olis, in thecounty of Marion and 4State o Indiana7 liaveinvented certain new vanduseful Improvements in Flushing-- Valves, of which the following isaspeci- The object of my invention is to supply. A

ficatio produce a lushing'valve, especially adapted for use inconnection with waterclosets, in which there is a total absence of theordinary eontrolling floats and in which the. closing of the valvewillbe controlled by the pressure ofy outflowing water from the flushingThe accompanying invention. l Figure 1 is a central vertical section;Fig. 2 a raginentary similar section of a modilied form; lFig. 3 adetail of the structure drawings illustrate my shown in Fig. 1, showinlthe osition of the parts when vthe initial va ve is first opened andFig. la similar detail showing .the positions of the pai-ts during freeout-- flow from the {iushing supply;

inthe fore thereof is a s ider25 upon the 26 which serves to hold inplace a pac ing .ring or valve 27 which seats upon an an nularvalveseat-28 formed at the upper end Patented Auge, 191e; v

of valve 22 around the bore thereof. Spider.

25, near its lower end, is provided with shoulders 29 adapted to engageshoulders 31 formed on the valve 22 and thus limit the movement 'of thevalve relative to seat 28. vIn order to move the two valve members'upwardly away from their. seats against the pressure 'of `water withintank 10, I journalf,l

which projects into the casing and Vis pro in casing 18, a shaft 33, theinner end'V of f videdwith a crank arm 34 cai'iiying a wristf pin 35which projects into a slot 36 formed Y in the lw'er end of a 'link 37,the up er end of which is connected to spider 25. ecured to theouter'end of shaft 33 is an `operating handle or lever. 38 which hassufficient weight to pull the valves down upon their seats. Shaft33-liasits axis arranged to one side ofthe axis of the valves fora purpose-whichlwill appear.

The operation is as follws:-Witli the parts in the position shown inFig. 1, water introduced into tank l() through pipe 13, will act uponthe upper faces kof ythe two valve members to hold them totheirseats 19and 28, forming an air cushion 'iii the upper end of the-tank. yWhenlever 38 is raised the valve 2G-27 will first be witlh4 'drawn from itsseat 28 andthis maybe dona-"l" with comparative ease because the .valveis' comparatively small, the parts coming into the osition shown in Fig.3. y'l.`l1ewater will egin to fiow through the bore of the valvemember22 whereupon further up ide crank `pin v35lias been carried beyondltheaxis-of the valve so that the pressureof the flowing Water upon theuplper faces of the a ,ves will serve to ho dy lever 38 from L downwardmovement and thus the valves Willbe held open. The weight of .lever 38is just'enough to bring the valves to closed position'when there isabout eight cauces du .ahalf' pound, (more or less dependmg'u onopressure uponltheupper of .the valves and. consequently, as ,soon astheout-v iovsfafrom tanl: L1() has been vsuliicient-'to' re? i the pressure,-thereinl 'to approximately the'weight ci lever 38 tending to' pr ucereturn movement of shaft 33) the said lever iviilserveto automaticallyreturn the valves to clawed position and thus cut od the Hushe'lewv; .Yv

Actual practicehas `deino'lwtrated that the valvey meehanism operateswith certainty Aaa fing crippling and. .iniii:orrnity It will be seenythat, by

closing the supply valve 51,' which is in the Ifeed line leading to,pip`e 13, and disconnectmay be rea ilywithdrawn for the removal `ofsediment and for the replacement of the' pacltin rings 23 and 27. A

in t e 4form shown in Figs. 1, 3- and 4, there is a eontinuous inflow ofywater from the su ply .pipe 13 during the lushingactionportion of the.iiushing iiow. In thestructure shown Ain Fig. 2 all of the parts areidentical with the parts similarly ldesig usted .in Fig. l, but uard 14is omitted.

- in 'this forni the supp y pine 13 is closed at its inner end andcommunicates with the. l interior of the tube 12 by. means of twoaxially alined openings 52 and 53 into which a pin 54 carried-by cap 26,isprojected during the time the valves arein olen position, as clearlyshown in Fig. 2. he pin 54: does not need to lit openings 52 and 53 veryvtightly but, byu'en'tering said openings,- the l iniow' of water `frompipe 13 during the Y readily unilied without in any manner.

time the valves are in open position, is.

practically stopped. v

It is to boeunderstood that, while have, shown the-valve members asbeing -composite in order to facilitate the openingthereof againstaccumulated pressure, yet

my inventionis by no means limited to such'.

a construction, for it is readily apparent that the two nested valvemembers mightfbe changing the operation of the device other thanincreasing the amount ofi force necesv sarA to get an `initial openingthereof.

n thev normaloperation'ofbrny device itA is entirely probable that the'velocity of out,- ow from the apparatus to the bowl will decrease, asthe amount of water and pressure in the tank decreases., to a suilicientextent to lgradually diminisli'the fiow from the bowl 17the entire valvemechanism` n the modification shown in Fig. 2l this inotv is preventedduring the major' `ating member, and a cra tween said operatingmember'and' the valve,

v'pending' upon the p ythe 'purpose set forth. A

adapted to engage the valve 22 and vserve to hold the same open until asuilcient pressre has accumulated above the valve. The

vspring 42 will serve to hold the, acking ring 23 when a` 4shortdistance above t e valve seat 19, this distance being less than enoughto.,

accommodate the full flow entering tube 12 from pipe 13, so thatwhenever the' valve is brought down upon the spring, there 'willinevitablybe a gradual vaccumulation of ressure on top of the valve ,soas to insure its ultimate closing, although there will be for a shorttime a flow of suiiicient amount to insure. the refilling of the bowlafter it has been flushed.

I-claim as my invention:

1. In a valvestructure having a lvalve seat, a val-ve movable'tow'ardand fromI said seat, an operating member, and'intermed'iateconnectionsbetween said operating member and the valve arranged in such manner thatpressure upon the lvalve toward its seat will normally tend to drivethe' operating member in closing direction but, when the valve is inopen position will tend to drive the o erating sure upon the open valvein excess'o the norma closing force of the operating` member will serveto-hold the `valve open.

2..In a iiushin'g valve, the combination with. a' closed liushingtank,having a supply pipe leading` thereto and an outflow passage leadingtherefrom, of a valve arranged 'be-I tween thetank and outiow ssage, anoperconnectionY bewhereby pressure upon the valve tending to member inopening direction, where y resclose the same will act upon the operatingmember to move it in eitherdirectiomdeA A valve structure comprising `amain Ibody having a valve seat, a valve arranged to coperate with saidseat, an inletstructure arranged within, the main body and havingopenings communicating therewith, and a filling member carried by thevalve and cooperating with 4the .openings in the inlet structure whenthe valve is opened to reduce inflow, for the purposes'- set forth.

4. In afvalve structure having a valve seat,
